Be it known that I, EMIL GATHMANN, a citizenof the United States,residing at South Bethlehennin the county of Northampton and StateofPennsylvaniahave invented certain new and useful Improvements inProjectiles, of which the following is a specification.

My invention relates to that class of projectiles provided. withsoft-metal caps; andit consistsin the means of securing and retainingthe said-caps in place upon the projectiles, as fully set forthhereinafter and as illustrated in the accompanying drawings, in which-Figure 1 is a side view of a projectile with the cap in cross-sectionthereon, showing the improved retaining means. Fig. 2 is the same,showing the form 4of the cap before it is secured and the die forsecuring the same. Fig. v3 is a detached view'of the retainer, and Fig.4

-is a'detachedwsectional view showing the form of the cap before it issecured inplace.

sTheprojectile is of any suitable construction, with a `body portion Aand a pointed end which, as shown, is conoidal, and adjacent to the saidend is an annular recess 1, extending' 'circumferentially and ofasuitable cross-section to coincide with the cross-sectional form of aretainer C, the latter being in theform o t' a divided-ring, the innerportion of which lits the said recess. -The soft-metal point B hasarsocket adapted to receivethe Apointed end of the projectile andhas'alsoan annular recess of a form corresponding to the project- .mgportion of the retaining-ring C, the cap extending back beyond the saidringand f1ttingelose against the surface of the projectile, as shown mFig; 1, wherebythesaid ring serves asa means of securely retaining thecap upon the point of the projectile.

In the application of the-cap to theprojectile the cap is rst formedwith a socket and an annular enlargement, Fig. 4, of such internaldimensions that it will. pass readily over the retaining-ring andexternally greater in diameter than the body of the. cap. The parts areput 1n position, Fig.l2, and the cap is'then passed through the openingof a die D and, together with the projectile, is carried onward untilthe action of the die serves tom Il m-n-rrd compress the enlargement ofthe cap., bringing it to the same diameter as the remaining portion ofthe cap and extending and spreading the projection 3 over and around theretaining-ring and onto the face of the projectile.

Preferably the retainer is of hard metalas, for instance, hard steelsothat the annular projection or 'lip of the cap will readily liow overthe same during the passage of the cap through the die. Further, thering is preferably split, so that it can be expanded to pass it overthepoint of the projectile and .into the groove or recess and will thencontract, so as to fit closely the said groove.

When the cap is applied, it wholly incloses the ring and holds the endstogether, so that they cannot separate and permit the cap to becomeloose.

It will be evident that the ring may be of any suitable cross-sectionalform, the grooves in the projectile and cap corresponding thereto, andthat it may be made of any desired material.

Without limiting myself to the construction and arrangement shown, Iclaim- 1. A projectile having a pointed end, combined with a soft-metalvcap having a socket receivingsaid end, and with an annular retainerfitting an annular groove in the projectile and corresponding groove inthe cap and wholly-inclosed by the latter, substantially as set forth.

2. A'projectile having a pointed end combined witha soft-metal caphaving a socket* receiving vsaid end, and with an annular retainerofharder material than the projectile,

fitting an annular groove in the projectile and corresponding groove inthe cap and wholly inclosed by thelatter, substantially as set forth.

3. A projectile having a pointed end and annulargroove adjacent totheend, combined with a cap of soft metal having a socket receiving the endof the projectile, and an annular groove coinciding with that of theprojectile, and a retainer consisting of a split ring fittingandinclosed in said grooves, substantially as set forth.

4. A projectile having a pointed end and annular groove adjacent to theend combined with a cap of softl metal having a'soeket re-Iutestimonywhereof Ihave signed my name ceiving the end'of .theprojectile and an antao this specification in the presence of twosubnular groove coinciding with that of the pro-V scribing Witnesses. v,jectile, and a retainer .consisting ot' a split; ring EMIL GATHMANN. ofharder metal than the projectile fitting and Witnesses:

inolosed in said grooves, substantially as set WVM. S. HERMANY,
